HASP LOCK John Yanuslro, Pottstown, Pa., assignor of onehalf to Pete Bobovski, Parnassus, Pa.

Application February 23,

4 Claims.

This invention relates tocertain new and useful improvements in hasp locks, and the invention resides in the novelv detail construction of the parts and the arrangement thereof.

The primary object of this invention is to provide a hasp lock having a sliding bolt adapted to engage the hasp member in order to lock a closure in a closed position.

A still further object of this invention is to provide a hasp lock of the above mentioned character having spring retracting means and a turnbler spring pressed into engagement with a projection formed on the bolt.,

A still further object of this invention is to provide a hasp lock of the above mentioned character in which the lock construction is enclosed in a frame having suitable cut-out portions to receive the Working parts of the lock and an external casing capable of being removed for the purpose "f of making repairs to sections of the lock.

A still further object of this invention isto provide means between the lock frame and the external casing whereby the two will be locked together but may be unlocked by the use of an instrument provided for this purpose.

A still further object of this invention is to provide a hasp lock of the above mentioned character having a peculiarly shaped tumbler p rotected from the key hole by means of a separate partition mounted within the lock casing to prevent unauthorized persons from gaining access to the tumbler and operating the sliding bolt.

Other objects and advantages of the invention will become apparent during the course of thefollowing description forming a part of the speciiioation and in which,

Figure 1 is a top elevational view of the hasp lock embodying this invention;

Figure 2 is a top elevational view of the same showing the hasp hingedly connected to a closure and the vmanner in which the lock on the endY thereof is positioned for engaging and receivingV the eye loop;

Figure 3 is an enlarged fragmentary top elevational view of the lock per se;

fragmentary portion of the lock structure is shown to illustrate this feature;

Figure 6 is a longitudinal cross-sectional view 1934, Serial No. 712,672

ing bolt as projected into its locked position with 65 the hasp keeper; and

Figure 8 is a similar transverse cross-sectional view taken on lines 8 8 of Figure 4 looking in the direction of the arrows illustrating the manner in which the sliding bolt is held in its locked position by means of the spring pressedplunger type tumbler and showing the manner in which the spring acting upon the plunger or tumbler is employed for locking the twoparts of the' casing together.

In the drawing, the reference character A designates a hinged closure such as a door or the ke which swings into abutment with a door frame B.

Secured to the door frame B is a plate 5 having a hasp loop 6 which is of ordinary construction and is adapted to be received Within an opening 7 formed in a hinged hasp leaf Spreferably formed of strap iron and tapering from the end 9 to a reduced portion 10 so that the free end may be bent into Va loop as at 11 for being received between a pair of upstanding ears l2 formed on a securing plate 13. A bolt 14 is passed through the opening 15 formed in the ears 12 and extends through the loop 11 thereby allowing the hasp hinge 8 to swing about the pivot or bolt 14.

Secured to the free swinging end of the hinge leaf hasp 8 is a twopart lock casing including a metal block 1G having a transverse slot 17 registering with the slot 18 formed in the free swinging end of the hinged hasp leaf 8. Formed at right angles to the slot 17 and on opposite sides thereof arerbores 19 and 20 for slidably receiving a locking bolt 2l having formed intermediate its ends a projection 22 adapted to engage a locking tumbler which will be hereinafter fully described. Directly opposite the projection 22 is a projection 23 terminating in a circular portion adapted to travel in a bore 25 formed in the block 16, which bore extends from the center portion of the locking casing to one end thereof and terminates inwardly as at I-26 which forms an abutment for one end of a coil spring 27 which has its opposite end impinging upon the circular portion 24: of the projection 23 whereby the bolt 21 will be normally retracted from its locking position within the hasp loop 6.

It will be noted that the block 16 is slotted as at 28 and 29 on opposite sides of the sliding bolt 21 for receiving the projections 22 and 23 along with the disk-like portion 24 whereby the bolt 24 may slide freely within the lock casing unless otherwise disturbed.

It is intended to secure the block 16 to thefree end of the hinged hasp by means of bolts 30 extending therethrough or if desired, the block 16 may be Welded or otherwise rigidly secured to the hinge hasp 8.

Directly at right angles to the bore 20 formed in the casing block 16 is a bore 31 forslidably receiving a tumbler block 32 having a laterally extending portion 33 offset from the sliding tumbler block 32. A partition 34 extends upwardly into the bore 31 upon which the tumbler block 32 may rest when the parts are in their locked position. A key hole slot 35 is formed in one face of the block 16 whereby the ward on a key 36 may engage the tumbler block 32 for the purpose of shifting the tumbler block against the tension of a coil spring 37 to unlock the sliding bolt 21 whereby the coil spring 27 will retract the bolt 21 from its locked position.

t will be noted that the coil spring 37 has one of itsends engaging the tumbler block 32, while the opposite end extends through the bore 31 and is received in a cut-out portion 38 formed in a rectangular box-like casing 39 which may be slipped over the block 16 and secured in place by means of bolts 40 extending through the rectangular box-like casing 39 and being anchored in the hinged hasp leaf 8.

Formed on opposite sides of the sliding connection between the lock casing block 16 and the rectangular box-like casing 39 are openings 41 and 42 in direct communication with the bore 31 for allowing the insertion of an instrument or tool to engage the coil spring 37 in order that the coil spring may be moved to allow displacement of the box-like casing 39 from the block 16.

One end of the sliding bolt 21 projects through the end of the block 16 and also through the opening 44 in the box-like casing 39 and said sliding bolt 21 is further guided by means of a projection 45 formed on the free swinging end of the hasp leaf 8 having an opening 46. The projection 45 also forms an abutment for the outer box-like casing 39 for holding the same against longitudinal displacement.

A cover plate 48 may be held in place by the bolt 40 and said cover plate 48 is provided with a key hole opening 49 adapted to register with the key hole slot 35 formed in the block 16. A handle 50 may be secured to the cover 48 for the purpose of swinging the entire structure about the pivot 14 after the bolt 21 has been retracted from its locking position to move the free end of the swinging hasp hinge 8 out of engagement with the hasp loop 6.

It is to be understood that the form of the invention herewith shown and described is tol be taken as a preferred embodiment of the same and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the sub-joined claims.
